This is you first post, so I'm going to make assumptions because I don't know anything about you.
Until you have your passport in hand with a visa in it, never make any plans. Don't buy non-refundable airline tickets, don't sell all your furniture, don't give up your housing or lease. We've seen examples on here of people who do their interview, are told their visa is approved, and then get stuck in Administrative Processing.
People can spend days, weeks, months, or even years in Administrative Processing. It's individualized based on what they think they need to approve your visa. You can use what happened to others as a guideline, but it's just that. Your case can (and appears to) be different.
You need to start thinking about what you're going to do if you don't get your passport and visa back before August 13th. At the very least, you may have to change your departure date.
No one can tell you how long you will be in Administrative Processing.
